Specification of Letters Patent.

Patented Dec. 12, 1916.

, To all whom z't-may concern:

Be it known thatI, OHAUNCEY D. Snnrr, a citizen, of .the United States, and a". resident Off. Nehawka, in the county of Cass and State of Nebraska, haveinventeda new andlmproved.sash Pulley, of which the following is a full, clear, and exact description.

This, invention relates to sashpulleys for use with window frames andsnmlarcon struct ons, and. has reference more part1cularly to'a-r sash pulley which comprises a bodyhavingspaced sides. and asheave or pulley wheel 'journaled between the sldes,

the body having. a partadapted to seatupon the top of a window frame and constituting means-forthe attachment of the. deviceto the window frame, the'body also having a partadapted to rest against the side of the windowframe, below the top thereof.

An ObjESClZOf1l1116 inventionisto provide a sash pulleywhichican be securely fastened} to the window frame 1without mortising or counter-sinking, by means:of which orifices giving'rise to drafts can beeliminated, and which can be used with equal facility with mortised top. and. flat; top window. frames.

The invention consistsin the construction andrombination. of, parts to; be more :fully described hereinafte anchparticularly set forth in the claims. a

Reference is to be had to the accompanying drawings forming "part of this specification, in which similar .charaoters of; reference indicate corresponding parts in all the views, and in which+- Figure 1 is a side elevation of the upperpart of a window frame, showing one form of my invention applied thereto; Fig. 2 is a side view of the upper portion of a window frame, showing two of the sash pulleys mounted upon the frame; Fig. 3 is a perspective view of one form of my sash pulley; Fig. 4 is a view similar to Fig. 1, showing a different form of the sash pulley applied to the window frame; Fig. 5 is a view similar to Fig. 2, illustrating two of the sash pulleys shown in Fig. 4; and Fig. 6 is a perspective view of the last-mentioned orm of my invention.

Before proceeding to a more detailed eX- planation of my invention it should be understood that the two forms of the device illustrated and described herewith are for use respectively, withmortised top window frames, and fiat top window. frames. Of these, the former are generally used in frame buildingsandthe latter in stone or brick buildings.

Referring more particularly to the drawings, Figs. 1, 2 and 3, the window frame has sides lO and a top 11, the sides being ex tended abovethe top and having the ends of the latter mortised thereto. Within the frame are slidably mounted the window sashes 12, to which the ends of the sash cords 1.3 are fastened. At the oppositeiends,-the sash cords have the usual sash weights 14.

I prefer to fashion my sash pulleys from sheet or plate metal. The body of the devicev is produced by bending the. plate or sheet upon itself sothat spaced sides 15 are formed which are joined by a preferably rou'ndedtop 16.: J ournaled between: the upper parts of the spaced sides 15 is the sheave or pulley wheel. 17 mounted upon a suitabletrunnion or pintle 18. Neartheir rear edges, the sides 15 have upwardly extending slots or cutaway parts 19 which are substantially parallel to the rear edges of the sides. These slots form downwardly extending feet 20. I prefer to have the forward or outer edges of the slots inwardly bent'to formparallel-fianges 21. The'outer edges of the sides 15 are inwardly inclined and the sides thus: form tapered extensions 22. y

The forum of the sash pulley above describedywhen in position, receives the projecting upper end 10'" of the window frame side 10, the feet 20'resting upon thetop 11 of the window frame, and the extensions 22 against the side 10, as is clearly shown in Fig. 1. With this construction of window frame no other means are necessary for fastening the sash pulley in position. It may be desirable to have the slots 19 of such size that the device can be driven firmly into position upon the end of the frame side 10. The frictional contact thus obviates the necessity for otherwise securing the sash pulley in place.

It will be understood that it is customary to employ two sash pulleys, as is shown in Figs. 2 and 5. These are preferably mounted side by side, as illustrated.

The window frame shown in Figs. 4 and 5 has sides 23 and a top 24. The sashes 25 are slidably mounted within the frames, and have the ends of the sash cords 26 attached thereto. At the opposite ends, the sash cords are attached to the usual sash weights 27. The second form of my device is likewise preferably fashioned from sheet or plate metal bent upon itself to form two spaced sides 28 connected by a rounded top 29. At the rear, and below thetop, the sides are cut away at 30. The outer edges of the sides are like in the first-described device, inwardly inclined, and form tapered extensions 31 at the lower portions thereof. At the top of the extension 31 the sides have outwardly-bent parts 32 forming oppositely disposed feet. The pulley wheel or sheave 33 is journaled between the upper parts of the sides 28, by means of a suitable pintle or trunnion 34. This form of my invention is arranged to seat at the upper corners of the window frame as is shown in Figs. 4 and 5, the feet 32 resting upon the top 24:, and the extensions 31 against the sides 23. To secure the device in place, screws or nails 35, driven into the window frame through the openings provided for the purpose in the feet 32, are employed.

It will be understood that the sash cords pass over the pulley wheels or sheaves in the usual manner, openings for the sash cords being provided in the top of the window frames.

If so desired, the form of my invention shown in Figs; 1, 2 and 3, may be provided with nail or screw holes 21, near the lower ends of the flanges 21. These openings are adapted to receive screws or nails serving to hold the device against lateral displacement, should it be necessary.

Having thus described my invention I claim as new, and desire to secure by Letters Patent 1. A sash pulley mounting comprising a single strip of sheet metal bent upon itself to form a pair of spaced apart downwardly extending side members, and a sheave ournaled between said side members, said side members having feet at the rear adapted to rest upon the top. of the window frame,

and having downward extensions, the rear edges of which are adapted to lie against the vertical end of the window frame.

2; A sash pulley comprising a body fashioned from sheet metal bent upon itself to form spacedsides, and a sheave journaled between said sides, said sides having at the rear, feet adapted to rest upon the top of a window frame, and having at the front spaced downward extensions the front edges of which are adapted to rest against a side of the window frame.

3. A sash pulley comprising a body having spaced sides, and a sheave journaled between said sides, said sides being cut away at their rear edges to form feet adapted to rest upon the top of a window frame and having at their lower ends spaced extensions the rear edges of which are adapted to rest against a side of the window frame, below the top thereof, said feet constituting means for attaching the device in place.

A. A sash pulley comprising a body fashioned from sheet metal bent to form spaced sides, and a sheave journaled between said sides, nearthe top thereof, said sides'being cut away at their rear edges to form feet adapted to rest upon the top of a window frame, and having at their lower ends spaced apart tapered extensions the rear edges of which are adapted to rest against a side of the window frame, below the top thereof, said feet constituting means for attaching the device in place upon the window frame.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
